%X Nowdays,the DSP core waiting time is longer in some IEEE 802.11a implementations based on multi-core DSP,which can not take full advantage of its high-performace computational capabilities.This paper combined the characteristics of multi-core DSP,using coarse-grained pipeline between DSP cores and fine-grained pipeline in single DSP core to enhance execution efficiency of multi-core DSP.It implemented on target heterogeneous mutli-core DSP with a complete IEEE 802.11a receiver baseband processing.The experiment show that this method not only guarantee the system throughput and real-time,but also improved the DSP core average utilization compared similar works.
